In art, an error is rarely fatal […] And because an error is generally more productive than counter-intuitive, it is often met with a certain recognition, the one that is usually reserved for the feeling of bedazzlement by a new idea, or the revelation of something hitherto unthought of. Walking sideways, the crab is an error in itself and sometimes, even often, it is a precious vehicle of reflection that can evolve into a method on its own.
